When I have cruise control on but not in use at that moment the car will engage cruise on its own. It does this at a high rate of acceleration with no Rhyme or Reason as to why. I have to be quick to get it to stop because of the high rate of speed. I do not use the cruise control anymore on my vehicle because of being unsafe. I have been lucky a couple of times I have not rammed into the vehicle in front of me through no fault of mine except for having cruise control on. No it has not been examined or inspected. The problem has not been confirmed by the dealership or and independent service center. It has been confirmed by various drivers of my car. None of them will use cruise control anymore.

While letting off the gas in order to break, the accelerator pedal went to the floor on its own for about 3 seconds. Pushing on the break stopped the accelerator.
NHTSA complaint #11461418 — an unverified report by a vehicle owner.
SERVICE ENGINE LIGHT AND GAS LIGHT CAME ON. CODE READ AT AUTOZONE INDICATED PO135- OXYGEN SENSOR. TWO DAYS LATER, BOTH CHECK ENGINE LIGHTS CAME ON, SECURITY, BATTERY AND GAS LIGHTS. EVEN REVVED UP AND HAD OTHER ISSUES WITH FUEL ECONOMY AND COMPRESSOR KICKING ON AND FAILING TO START. OTHER ISSUES, POPPING NOISE WHEN TURNING STEERING WHEEL. THE CONSUMER STATED THE MANUFACTURER WAS CONTACTED. THE MANUFACTURER OFFERED A LOYALYTY CERTIFICATE A LEASED VEHUCLE OR A POSSIBLE REIMBURSEMENT OF 500.00 FOR REPAIRS. NEITHER OF THE REMEDIES SATISFIED THE CONSUMER. THE CONSUMER REQUESTED TO HAVE THE VEHICLE REPAIRED AT NO COST OR BE REIMBURSED 3,500.
NHTSA complaint #11405509 — an unverified report by a vehicle owner.
THE VEHICLE'S GAS TANK WON'T HOLD MUCH AND CLICKS AS IF FULL. ALSO, WHEN ON UNEVEN PAVEMENT OR GROUND, THE ⛽ GAS WARNING LIGHT COMES ON, EVEN AFTER GAS WAS JUST PUT IN. IN ADDITION, AT TIMES I SMELL A "BURNING ELECTRICAL" SMELL AND THE HEADLIGHTS GO OUT, THE BRIGHTS FAIL TO "CLICK" ON OR GOES OFF BY ITSELF. THE TURN SIGNAL LIGHTS HAVE TO BE TURNED MANUALLY TO BLINK. ALL TURN SIGNAL LIGHTS HAVE BEEN REPLACED MULTIPLE TIMES AND THIS DOES NOT FIX THE PROBLEM. THE BACK TURN SIGNALS WORK AND LIGHT UP, BUT NOT THE FRONT & BLINK AT A FASTER RATE. EVEN ONE SIDE HEADLIGHT ENGAGEMENT WAS REPLACED AND THE PROBLEMS STILL EXIST.

I KEEP GETTING MY AIR BAG WARNING LIGHT COMING ON, THE ABS, AND THE CHECK ENGINE SOON LIGHT, THEY WONT GO OFF. THE FUEL LINE THAT GOES INTO THE GAS TANK /NECK LEAKS WHEN GAS GETS PUMPED INTO IT. THE ODOMETER MILEAGE DISPLAY P.R.N.D.L. WONT WORK AND NEITHER WILL THE TEMPERATURE GAUGE INDICATOR FOR THE CLIMATE CONTROL GAUGE.
NHTSA complaint #10860618 — an unverified report by a vehicle owner.
YOU COULD SMELL GAS INSIDE AND OUTSIDE THE CAR. I TOOK IT TO MY GARAGE AND THEY WENT ALL OVER IT AND COULD NOT FIND ANY REASON FOR THE SMELL. IT DIDN'T MATTER IF THE GAS TANK WAS FULL OR HALF FULL. WHEN THE WEATHER WAS WARM IT WAS MUCH WORSE. I AM WONDERING IF THERE HAVE BEEN ANY OTHER COMPLAINTS ABOUT THIS PROBLEM. I AM AFRAID THE CAR WILL CATCH ON FILE.

EVERY BUICK OWNER, I HAVE TALKED TO AT ABOUT 80,000 TO 100,000 MILES HAS TO REPLACE INTAKE MANIFOLD AND BOLTS. THIS IS ABOUT A $1200.00 JOB, GASKETS AND BOLTS SHOULD LAST A LOT LONGER.
NHTSA complaint #10678391 — an unverified report by a vehicle owner.
WHILE BACKING INTO MY DAUGHTER'S ATTACHED GARAGE, THE GAS LINE RUPTURED AND LEAKED A LOT OF GASOLINE BEFORE I SHUT-OFF THE IGNITION. I PROMPTLY RE-STARTED THE CAR AND BACKED IT OUT OF THE GARAGE, UNWITTINGLY RISKING IGNITING THE GASOLINE IN THE PROCESS, BUT STILL AFRAID OF THE GAS/FUMES IN THE GARAGE IGNITING AND BURNING US, THE CAR AND THE HOUSE DOWN! WE GOT A WATER HOSE AND BROOM AND SWEPT AS MUCH OF IT OUT OF THE GARAGE AS WE COULD. WE WERE LUCKY. THE POINT OF THIS COMPLAINT IS THAT THERE ARE PROBABLY TENS OF THOUSANDS OF G M CARS BEING DRIVEN AND PARKED IN GARAGES WITH QUITE OLD, DETERIORATING GAS LINES WHOSE DRIVERS ARE TOTALLY UNAWARE OF IT. OUR EXPERIENCE, ALONE, COULD HAVE BEEN A DISASTER. MY SON-IN-LAW HAS EXPERIENCED THE SAME PROBLEM WITH HIS 1995 OLDSMOBILE CIERA, ALTHOUGH HE BELIEVES THAT THE SQUIRRELS AROUND HIS HOME LIKE TO CHEW ON THE PLASTIC GAS LINES. IT SEEMS TO ME THAT THESE OLD PLASTIC GAS LINES REPRESENT AN ENORMOUS RISK TO THE SAFETY OF MILLIONS OF PEOPLE WHILE THEY'RE NOT EVEN IN OR NEAR THE SOURCE OF IGNITION. THEY COULD, IN FACT, BE IN BED AT THE OTHER END OF THE HOME WHEN IT ALL BLOWS-UP!

I HAVE A 2000 BUICK CENTURY LIMITED AND THE TRANSMISSION HARSH SHIFT 1234, WHEN HOT AND SOMETIMES COLD, I KNOW THAT IT NEEDS A NEW 1234 UP SHIFT SOLENOID AND TO BE INSPECTED FOR FAILED PARTS ETC, ALSO THE ODOMETER,FUEL GAUGE,AND WINDOW REGULATORS/MOTORS HAVE FAILED, THE ODOMETER IS OUT AND FUEL GAUGE FLOATS AND WINDOWS HAVE FAILED DUE TO BAD DESIGN OF MOTORS/REGULATORS AND MY AIRBAG LIGHT IS ON AND EACH 4T65- E TRANS AND MANY BUICK TRANS LIKE THE ONE ABOVE HAS HARSH SHIFT AND COULD CAUSE DAMAGE AND CAUSE TRANS TO FAIL. AND THE PROBLEMS ABOVE WILL BE FOUND IN MANY BUICK CENTURY AND GM SHOULD FIX THE ISSUES ABOVE FOR FREE IT IS A DANGER FOR THE TRANS TO FAIL AND ODOMETER/GEAR SHIFT SELECT TO FAIL BECAUSE MOST PEOPLE WILL NOT KNOW WHAT GEAR THEY ARE IN, AND THE TRANS COULD LOCK AND CAUSE A WRECK OR A HUGE INJURY OR WORST. AND THE TRANS 1234 UP SHIFT PRESSURE CONTROL SOLENOID NOT KEEPING THE RIGHT PRESSURE COULD DAMAGE THE TRANS, AND EVEN IF THE TRANS IS BOUGHT USED IT STILL HAS THIS PROBLEM AND IS THE SAME 4T65-E TRANS AND GM NEEDS TO FIX THIS FOR FREE THERE ARE MANY COMPLAINTS AND ISSUE WITH THE 2000 BUICK CENTURY,REGALS ETC WITH THIS TYPE OF TRANS. AND SHOULD BE FIXED RIGHT AWAY BEFORE IT BECOMES A COSTLY REPAIR OR WRECK! AND THE TRANS SHOULD BE CHECKED FOR ANY OTHER FAILURES. FOR FREE.

THE GAS GAUGE IS NOT ACCURATE EVEN THROUGH IT SAYS NO FUEL IT STILL HAS PLENTY IN THE TANK. THE CAR REVERSE UP AND GOES ON ITS OWN WITHOUT USING THE GAS PEDAL AND WHEN YOU PUT THE BRAKES ON IT SHUTTERS. THE WINDOWS DON'T WORK VERY WELL ANYMORE.
NHTSA complaint #10524693 — an unverified report by a vehicle owner.
STARTED CAR AND GASOLINE STARTED GUSHING OUT FROM BENEATH THE CAR BETWEEN THE DRIVER'S DOOR AND THE FRONT WHEEL-WELL. AS THE CAR WAS PARTLY IN THE GARAGE, I DROVE IT OUT OF THE GARAGE AND TURNED THE ENGINE OFF. THIS STOPPED THE FLOW OF GASOLINE. A MECHANIC LATER DETERMINED THAT THE PLASTIC GAS LINE HAD FAILED AND, AFTER CUTTING-OFF THE DAMAGED PART, HE SPLICED THE LINE BACK TOGETHER WITH A BRASS COUPLING. THAT SEEMS TO HAVE TAKEN CARE OF THE PROBLEM, FOR NOW. THE REALLY SCARY THING IS THAT THERE ARE HUNDREDS OF THOUSANDS OF GM CARS "OUT THERE" IN GARAGES AND ON THE ROAD WITH DETERIORATING PLASTIC GAS LINES! PROBABLY SOME OTHER BRANDS, AS WELL. AN ACQUAINTANCE OF MINE HAD THE SAME GAS LINE FAILURE ON HIS 1996 OLDSMOBILE CIERA.
